Keyword factor BETON_GLRC
===========================

This keyword factor is used to define the concrete material that will be supplied to the BETON/MATER keyword of DEFI_GLRC/RELATION =' GLRC_DM '.




Operand CODIFICATION
---------------------

This operand works in the same way as the MAZARS keyword.

♦ CODIFICATION= 'EC2'|'TEST'

• 'EC2': indicates that the parameters used in the definition of materials come from codification EUROCODE 2.

• 'ESSAI ':indicates that the parameters used in the definition of materials come from test.




Case where CODIFICATION =' EC2 '
~~~~~~~~~~~~~~~~~~~~~~~~~~~

♦ unite_ CONTRAINTE

Unit of constraint for the problem :math:`\mathit{MPa}` or :math:`\mathit{Pa}`: Mega-Pascal or Pascal. Entering this operand is mandatory, as it is necessary to return the material parameters to the unit system used to do the study.

♦ CLASSE

The compressive strength of concrete is designated by strength classes related to the characteristic strength measured on a cylinder or on a cube, in accordance with EN206 -1.

The classes available in the operator are all those defined in EUROCODE2:

'C12/15" C16/20" C20/25" C20/25" C25/30" C30/37" C35/45" C40/50'

'C45/55" C50/60" C55/67" C55/67" C60/75" C60/75" C70/85" C80/95" C90/105'




Case where CODIFICATION =' ESSAI '
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In this case, the user must fill in the following parameters which will be formatted in a "material" concept in order to be in the format expected by DEFI_GLRC. The user must provide these characteristics in a system of units compatible with his study.

♦ FCJ: Peak stress during compression.

♦ EIJ: Young's module.

♦ EPSI_C: Peak deformation under compression.

♦ FTJ: Peak stress during traction.

◊ NU: Poisson's ratio. (0.2 by default)
